Description

アナログ信号入出力装置およびアナログ信号入出力装置の制御方法Analog signal input / output device and control method of analog signal input / output device
　本発明はアナログ信号の入力および出力の少なくとも一方を行うアナログ信号入出力装置に関する。 The present invention relates to an analog signal input / output device that performs at least one of input and output of an analog signal.
　アナログ信号を入力する、または、出力する装置として、例えば、特許文献１には、較正手順実行機能および較正手順表示機能付のプロセス入出力装置が開示されている。詳細には、当該プロセス入出力装置は、入出力回路の較正試験の工程に応じて、ＬＥＤの点灯を制御する。 As a device for inputting or outputting an analog signal, for example, Patent Document 1 discloses a process input / output device having a calibration procedure execution function and a calibration procedure display function. Specifically, the process input / output device controls the lighting of the LED according to the process of calibration test of the input / output circuit.

　一方、アナログ信号入出力装置と外部機器とを接続した場合、適切に接続できたか否かの確認を行う必要が生じ得る。また、アナログ信号入出力装置の運用中に障害が発生した場合、原因を特定する必要が生じ得る。例えば、当該障害がアナログ信号入出力装置に起因しているか、あるいは、アナログ信号入出力装置の外側（配線不良、接続先の機器の故障）に起因しているか等を特定する必要が生じ得る。このような場合、アナログ信号入出力装置におけるアナログ信号の入出力レベルを確認することが重要となる。 On the other hand, when the analog signal input / output device and the external device are connected, it may be necessary to confirm whether the connection can be properly made. In addition, if a failure occurs during operation of the analog signal input / output device, it may be necessary to identify the cause. For example, it may be necessary to specify whether the failure is caused by the analog signal input / output device or by the outside of the analog signal input / output device (wiring failure, failure of connected device). In such a case, it is important to confirm the input / output level of the analog signal in the analog signal input / output device.
　しかしながら、上述のような従来技術は、アナログ信号の入出力レベルをユーザに示すといった観点に基づいた技術ではない。例えば、アナログ信号の入出力レベルを表示するためには、アナログ信号入出力装置に、７セグメントＬＥＤ、液晶表示器、アナログメータ等のアナログ信号の入出力レベルを表示する構成を設置する必要がある。アナログ信号入出力装置に該構成を設置すると、製造コストが高くなる。また、アナログ信号入出力装置に上述のような構成を設置するためには、該構成を設置するためのスペースを設ける必要が生じる。 However, the prior art as described above is not a technology based on the point of showing the user the input / output level of the analog signal. For example, in order to display the input / output level of an analog signal, it is necessary to install a configuration for displaying the input / output level of an analog signal such as a 7-segment LED, a liquid crystal display, or an analog meter in an analog signal input / output device . Installing the configuration in an analog signal input / output device increases the manufacturing cost. Further, in order to install the above-described configuration in the analog signal input / output device, it is necessary to provide a space for installing the configuration.

　〔実施形態１〕
　以下、本発明の一側面に係る実施の形態（以下、「本実施形態」とも表記する）を、図面に基づいて説明する。 Embodiment 1
Hereinafter, an embodiment according to one aspect of the present invention (hereinafter, also referred to as “the present embodiment”) will be described based on the drawings.
　§１　適用例
　図２は、本実施形態に係る、アナログ信号入出力装置の適用例の一例を示す図である。はじめに、図２を用いてアナログ信号入出力装置の適用例の概要を説明する。 Section 1 Application Example FIG. 2 is a view showing an example of an application example of the analog signal input / output device according to the present embodiment. First, an outline of an application example of an analog signal input / output device will be described with reference to FIG.
　図２に示すように、アナログ信号入力装置１は、センサ等のアナログ信号出力機器から入出力端子１１を介してアナログ信号が入力される装置である。例えば、アナログ信号入力装置１は、アナログ信号をデジタル信号に変換するＡ／Ｄ変換装置であってもよい。この場合、アナログ信号入力装置１はデジタル信号をコントローラ通信端子１７を介してコントローラ３に出力する。アナログ信号入力装置１は入力されるアナログ信号の入力レベルを検知する。アナログ信号入力装置１は検知したアナログ信号の入力レベルに応じて自装置に備わっているＬＥＤ（発光素子）１５の発光のオンおよびオフのパターンを制御する。そのため、アナログ信号入力装置１はアナログ信号の入力レベルに応じたパターンによってＬＥＤ１５を点灯させることができる。 As shown in FIG. 2, the analog signal input device 1 is a device to which an analog signal is input from an analog signal output device such as a sensor via the input / output terminal 11. For example, the analog signal input device 1 may be an A / D conversion device that converts an analog signal into a digital signal. In this case, the analog signal input device 1 outputs a digital signal to the controller 3 via the controller communication terminal 17. The analog signal input device 1 detects the input level of the input analog signal. The analog signal input device 1 controls the on / off patterns of light emission of the LED (light emitting element) 15 provided in the device according to the detected input level of the analog signal. Therefore, the analog signal input device 1 can turn on the LED 15 with a pattern according to the input level of the analog signal.
　なお、本実施形態では、入力されるアナログ信号の入力レベルを示すアナログ信号入力装置１について具体的な例を示す。一方で、図２に示すように、アナログ信号入力装置１の代わりにアナログ信号出力装置に本実施形態を適用してもよい。この場合、アナログ信号出力装置は、例えば、コントローラ３から出力されたデジタル信号をアナログ信号に変換する。アナログ信号出力装置は、アナログ信号によって駆動する機器（例えば、温調制御が必要なヒータ等）にアナログ信号を出力する。アナログ信号入力装置１の構成を適宜変更することにより、当該アナログ信号出力装置は、ＬＥＤの発光パターンによってアナログ信号の出力レベルを示す。 In the present embodiment, a specific example of the analog signal input device 1 indicating the input level of the input analog signal will be shown. On the other hand, as shown in FIG. 2, this embodiment may be applied to an analog signal output device instead of the analog signal input device 1. In this case, the analog signal output device converts, for example, the digital signal output from the controller 3 into an analog signal. The analog signal output device outputs an analog signal to a device (e.g., a heater requiring temperature control control) driven by the analog signal. By appropriately changing the configuration of the analog signal input device 1, the analog signal output device indicates the output level of the analog signal by the light emission pattern of the LED.
　また、本実施形態を、アナログ信号およびデジタル信号を入力する装置、アナログ信号およびデジタル信号を出力する装置、アナログ信号およびデジタル信号を入出力する装置等に適用してもよい。前記装置は、アナログ信号の入力レベルおよび出力レベルの少なくとも１つを示す。 In addition, the present embodiment may be applied to a device that inputs analog signals and digital signals, a device that outputs analog signals and digital signals, a device that inputs and outputs analog signals and digital signals, and the like. The device indicates at least one of an input level and an output level of an analog signal.
　前記の構成によれば、１つのＬＥＤの発光パターンによって、アナログ信号の入出力レベルを示すことができる。よって、アナログ信号の入出力レベルを７セグメントＬＥＤによって数字で表示する構成、液晶表示で示す構成、アナログメータ等で示す構成等に比べ、アナログ信号入出力装置の製造コストを抑えることができる。また、前記の構成によれば、アナログ信号の入出力レベルを示す構成を設けるために必要なスペースを抑えることができる。そのため、アナログ信号入出力装置の設計の自由度を向上させることができる。 According to the above configuration, the light emission pattern of one LED can indicate the input / output level of the analog signal. Therefore, the manufacturing cost of the analog signal input / output device can be reduced as compared with the configuration in which the input / output level of the analog signal is indicated by numerals by 7-segment LED, the configuration shown by liquid crystal display, the configuration shown by an analog meter or the like. Further, according to the above configuration, it is possible to reduce the space necessary for providing the configuration indicating the input / output level of the analog signal. Therefore, the degree of freedom in design of the analog signal input / output device can be improved.

　　　（相対値変換部１３１）
　相対値変換部１３１は、電圧検知部１３０から受信したアナログ信号の入出力レベルを、複数の異なるアナログ信号の入出力レベルのレンジのうち設定されている１つのレンジに対する相対値に変換する。詳細を以下に説明する。 (Relative value converter 131)
The relative value conversion unit 131 converts the input / output level of the analog signal received from the voltage detection unit 130 into a relative value with respect to one of the set ranges of input / output levels of a plurality of different analog signals. Details will be described below.
　図４は、アナログ入力（入出力）信号の電圧値とレンジに対する該電圧値の相対値との対応関係を示す図である。図４に示すように、本実施形態では、アナログ信号の入力（入出力）レベルのレンジは、レンジＡ「０Ｖ～＋１０Ｖレンジ」、レンジＢ「０Ｖ～＋５Ｖレンジ」およびレンジＣ「－１０Ｖ～＋１０Ｖレンジ」から選択され設定される。 FIG. 4 is a diagram showing the correspondence between the voltage value of the analog input (input / output) signal and the relative value of the voltage value with respect to the range. As shown in FIG. 4, in the present embodiment, the range of the input (input / output) level of the analog signal is the range A “0 V to +10 V range”, the range B “0 V to +5 V range”, and the range C “-10 V to +10 V "Range" is selected and set.

Also, the analog signal input device 1 may receive an input operation of the maximum value and the minimum value of the range in the support tool 4 and set an arbitrary input level range. For example, the set range may be stored in the storage unit 14 as the range information 141.

　相対値変換部１３１は、レンジ情報１４１を参照し、設定されているレンジに対するアナログ信号の電圧値の相対値を算出する。例えば、図４に示すように、レンジＡ「０Ｖ～＋１０Ｖレンジ」が設定されている場合、相対値変換部１３１は相対値を以下のように算出する。相対値変換部１３１はレンジの最小値である０Ｖを０％とし、レンジの最大値である＋１０Ｖを１００％として、入力されたアナログ信号の相対値を百分率として算出する。また、レンジＢ「０Ｖ～＋５Ｖレンジ」が設定されている場合、相対値変換部１３１は相対値を以下のように算出する。相対値変換部１３１はレンジの最小値である０Ｖを０％とし、レンジの最大値である＋５Ｖを１００％として、入力されたアナログ信号の相対値を百分率として算出する。また、レンジＣ「－１０Ｖ～＋１０Ｖレンジ」が設定されている場合、相対値変換部１３１は相対値を以下のように算出する。相対値変換部１３１はレンジの最小値である－１０Ｖを０％とし、レンジの最大値である＋１０Ｖを１００％として、入力されたアナログ信号の相対値を百分率として算出する。相対値変換部１３１は、算出したアナログ信号の相対値をＬＥＤ点灯制御部１３２に送信する。 The relative value conversion unit 131 refers to the range information 141 and calculates the relative value of the voltage value of the analog signal with respect to the set range. For example, as shown in FIG. 4, when the range A “0 V to +10 V range” is set, the relative value conversion unit 131 calculates the relative value as follows. The relative value conversion unit 131 calculates the relative value of the input analog signal as a percentage, with 0V being the minimum value of the range being 0% and + 10V being the maximum value of the range being 100%. Further, when the range B “0 V to +5 V range” is set, the relative value conversion unit 131 calculates the relative value as follows. The relative value conversion unit 131 calculates the relative value of the input analog signal as a percentage, with 0V being the minimum value of the range being 0% and + 5V being the maximum value of the range being 100%. Further, when the range C “−10 V to +10 V range” is set, the relative value conversion unit 131 calculates the relative value as follows. The relative value conversion unit 131 calculates the relative value of the input analog signal as a percentage, with the minimum value of the range of −10 V as 0% and the maximum value of range of +10 V as 100%. The relative value conversion unit 131 transmits the calculated relative value of the analog signal to the LED lighting control unit 132.
　　　（ＬＥＤ点灯制御部１３２）
　ＬＥＤ点灯制御部１３２は、アナログ信号の入力レベルに応じて前記発光素子の発光のオンおよびオフのパターンを制御する。 (LED lighting control unit 132)
The LED lighting control unit 132 controls the on / off pattern of light emission of the light emitting element according to the input level of the analog signal.
　詳細には、ＬＥＤ点灯制御部１３２は、相対値変換部１３１から受信した相対値に応じて、ＬＥＤ１５の発光のオンおよびオフのパターンを制御する。例えば、ＬＥＤ点灯制御部１３２は、記憶部１４に格納されているＬＥＤ１５の点灯パターンを示す点灯パターン情報１４２を参照し、ＬＥＤ１５の発光を制御してもよい。点灯パターン情報１４２は、ＬＥＤ１５の点灯パターンと相対値とを対応付けている情報である。ＬＥＤ点灯制御部１３２が行うＬＥＤ１５の発光のオンおよびオフの制御の一例について以下に説明する。 Specifically, the LED lighting control unit 132 controls the on / off patterns of the light emission of the LED 15 in accordance with the relative value received from the relative value conversion unit 131. For example, the LED lighting control unit 132 may control the light emission of the LED 15 with reference to the lighting pattern information 142 indicating the lighting pattern of the LED 15 stored in the storage unit 14. The lighting pattern information 142 is information in which the lighting pattern of the LED 15 is associated with the relative value. An example of on / off control of light emission of the LED 15 performed by the LED lighting control unit 132 will be described below.
　（ＬＥＤ１５の点灯制御の例１：所定の時間における、点灯時間と消灯時間とを制御）
　ＬＥＤ点灯制御部１３２は、所定の時間における、ＬＥＤ１５の点灯（オン）時間と消灯（オフ）時間とを相対値（百分率）に応じて決定し、ＬＥＤ１５の点灯または点滅を制御してもよい。例えば、ＬＥＤ点灯制御部１３２は１秒間におけるＬＥＤ１５の点灯と消灯とを以下のように制御する。相対値が０％の場合、消灯時間が１秒とし、ＬＥＤ１５を点灯させない。相対値が１０％の場合、点灯時間を０．１秒とし、消灯時間を０．９秒として、ＬＥＤ１５を点滅させる。相対値が９０％の場合、点灯時間が０．９秒とし、消灯時間が０．１秒として、ＬＥＤ１５を点滅させる。相対値が１００％の場合、点灯時間を１秒とし、ＬＥＤ１５を常に点灯させる。すなわち、相対値が高いほど、ＬＥＤ点灯制御部１３２は所定の時間におけるＬＥＤ１５の点灯時間が長くなるように制御する。 (Example 1 of lighting control of LED 15: Control lighting time and lighting off time in a predetermined time)
The LED lighting control unit 132 may control the lighting or blinking of the LED 15 by determining the lighting (on) time and the lighting off (off) time of the LED 15 in a predetermined time according to the relative value (percentage). For example, the LED lighting control unit 132 controls lighting and extinguishing of the LED 15 in one second as follows. When the relative value is 0%, the turn-off time is 1 second, and the LED 15 is not turned on. When the relative value is 10%, the lighting time is 0.1 seconds, and the lighting time is 0.9 seconds, and the LED 15 blinks. When the relative value is 90%, the lighting time is 0.9 seconds, and the lighting time is 0.1 seconds, and the LED 15 blinks. When the relative value is 100%, the lighting time is 1 second, and the LED 15 is always lit. That is, as the relative value is higher, the LED lighting control unit 132 controls the lighting time of the LED 15 in a predetermined time to be longer.
　（ＬＥＤ１５の点灯制御の例２：点滅周期を制御）
　次に、ＬＥＤ１５の点灯制御の他の例について説明する。ＬＥＤ点灯制御部１３２は、相対値に応じて、ＬＥＤ１５の点滅周期を決定し、ＬＥＤ１５の点灯または点滅を制御してもよい。 (Example 2 of lighting control of LED 15: control the flashing cycle)
Next, another example of the lighting control of the LED 15 will be described. The LED lighting control unit 132 may determine the blinking cycle of the LED 15 according to the relative value, and control lighting or blinking of the LED 15.
　例えば、相対値が０％の場合、ＬＥＤ点灯制御部１３２はＬＥＤ１５を点灯させない。相対値が２０％の場合、ＬＥＤ点灯制御部１３２はＬＥＤ１５を１秒間点灯させ、１秒間消灯させることによって点滅させる。相対値が４０％の場合、ＬＥＤ点灯制御部１３２はＬＥＤ１５を０．８秒間点灯させ、０．８秒間消灯させることによって点滅させる。相対値が６０％の場合、ＬＥＤ点灯制御部１３２はＬＥＤ１５を０．６秒間点灯させ、０．６秒間消灯させることによって点滅させる。相対値が８０％の場合、ＬＥＤ点灯制御部１３２はＬＥＤ１５を０．４秒間点灯させ、０．４秒間消灯させることによって点滅させる。相対値が１００％の場合、ＬＥＤ点灯制御部１３２はＬＥＤ１５を０．２秒間点灯させ、０．２秒間消灯させることによって点滅させる。すなわち、相対値が高いほど、ＬＥＤ点灯制御部１３２はＬＥＤ１５の点滅の周期が短くなるように制御する。 For example, when the relative value is 0%, the LED lighting control unit 132 does not light the LED 15. When the relative value is 20%, the LED lighting control unit 132 lights the LED 15 for one second and blinks it for one second. When the relative value is 40%, the LED lighting control unit 132 lights the LED 15 for 0.8 seconds and blinks it for 0.8 seconds. If the relative value is 60%, the LED lighting control unit 132 lights the LED 15 for 0.6 seconds and blinks it for 0.6 seconds. When the relative value is 80%, the LED lighting control unit 132 lights the LED 15 for 0.4 seconds and blinks it for 0.4 seconds. When the relative value is 100%, the LED lighting control unit 132 lights the LED 15 for 0.2 seconds and blinks the light for 0.2 seconds. That is, as the relative value is higher, the LED lighting control unit 132 performs control so that the cycle of blinking of the LED 15 becomes shorter.
　前記の構成によれば、複数の異なるアナログ信号の入出力レベルのレンジのうち設定されている１つのレンジに対する入出力レベルの相対値に応じて入出力レベルを示すことができる。すなわち、レンジの設定を変えることによって、異なる複数の前記レンジに対応させた、アナログ信号の入出力レベルを示すことができる。 According to the above configuration, it is possible to indicate the input / output level according to the relative value of the input / output level to one of the set ranges of input / output levels of different analog signals. That is, by changing the setting of the range, it is possible to indicate the input / output level of the analog signal corresponding to a plurality of different ranges.
　例えば、入力されたアナログ信号のレベルが設定されているレンジ内のレベルではない場合、相対値変換部１３１は相対値を算出しない構成としてもよい。前記構成によれば、入力されるアナログ信号と設定されているレンジとが対応していない場合、ＬＥＤ１５の発光制御は行われない。そのため、ユーザは入力されるアナログ信号と設定されているレンジとが対応していないことを認識することができる。 For example, when the level of the input analog signal is not within the set range, the relative value converter 131 may not calculate the relative value. According to the above configuration, when the input analog signal and the set range do not correspond to each other, the light emission control of the LED 15 is not performed. Therefore, the user can recognize that the input analog signal does not correspond to the set range.
　また、アナログ信号入力装置１は、複数のアナログ入力信号を同時に入力する構成としてもよい。例えば、アナログ信号入力装置１は、複数の入力端子１１ａと複数のＬＥＤ１５とを備えていてもよい。この場合、各入力端子１１ａと各ＬＥＤ１５とが対応付いていてもよい。ＬＥＤ点灯制御部１３２は各入力端子１１ａから入力されたアナログ入力信号のレベルを示すために当該入力端子１１ａに対応するＬＥＤ１５の点灯を制御してもよい。この構成においては、各入力端子１１ａと対応しているＬＥＤ１５を示す情報が記憶部１４に格納されていてもよい。ＬＥＤ点灯制御部１３２は該情報を参照し、各ＬＥＤ１５の点灯を制御してもよい。 In addition, the analog signal input device 1 may be configured to simultaneously input a plurality of analog input signals. For example, the analog signal input device 1 may include a plurality of input terminals 11 a and a plurality of LEDs 15. In this case, each input terminal 11a and each LED 15 may be associated with each other. The LED lighting control unit 132 may control lighting of the LED 15 corresponding to the input terminal 11a to indicate the level of the analog input signal input from each input terminal 11a. In this configuration, information indicating the LED 15 corresponding to each input terminal 11 a may be stored in the storage unit 14. The LED lighting control unit 132 may control lighting of each LED 15 with reference to the information.
　　（記憶部１４）
　記憶部１４は、例えば、フラッシュメモリ、ソリッドステートドライブ等の補助記憶装置であり、上述のレンジ情報１４１、上述の点灯パターン情報１４２等を記憶する。 (Storage unit 14)
The storage unit 14 is, for example, an auxiliary storage device such as a flash memory or a solid state drive, and stores the range information 141 described above, the lighting pattern information 142 described above, and the like.
　　（ＬＥＤ１５）
　ＬＥＤ１５は、ＬＥＤ点灯制御部１３２の制御に従い発光する。 (LED 15)
The LED 15 emits light in accordance with the control of the LED lighting control unit 132.
　ＬＥＤ１５は、アナログ信号とは別の信号の入出力時においても発光するように制御されてもよい。すなわち、ＬＥＤ１５はアナログ信号の入出力レベルを示す用途とは別の用途と共用されていてもよい。例えば、１つのＬＥＤ１５が、アナログ信号の入出力レベルを示す以外にも、他の信号（例えば、外部トリガの信号）の入力を発光によって示してもよい。ＬＥＤ１５が入力を示す対象の信号は、ユーザによるサポートツール４の選択操作を受け付けることによって、切り換えられてもよい。 The LED 15 may be controlled to emit light also at the time of input / output of a signal different from the analog signal. That is, the LED 15 may be shared with applications other than the application indicating the input / output level of the analog signal. For example, one LED 15 may indicate the input of another signal (for example, an external trigger signal) by light emission in addition to indicating the input / output level of the analog signal. The target signal whose LED 15 indicates an input may be switched by receiving a selection operation of the support tool 4 by the user.
　前記の構成によれば、用途ごとに複数の発光素子を設置する必要が無くなる。そのため、製造コストを抑えることができ、省スペースにも寄与することができる。 According to the above configuration, it is not necessary to install a plurality of light emitting elements for each application. Therefore, the manufacturing cost can be suppressed, and the space can be saved.
　（アナログ信号入力装置１の処理の流れ）
　図５は本実施形態に係るアナログ信号入力装置１の処理の流れの一例を示すフローチャートである。図５を用いて、アナログ信号入力装置１の処理の流れの一例について説明する。電圧検知部１３０はアナログ入力信号の電圧値を検知する（Ｓ１：入出力レベル検知ステップ）。続いて、相対値変換部１３１はアナログ入力信号の電圧値を相対値に変換する（Ｓ２）。続いて、ＬＥＤ点灯制御部１３２は、相対値に応じたパターンによって、ＬＥＤ１５を点灯させる（Ｓ３：発光制御ステップ）。アナログ信号の入力が終了した場合（Ｓ４でＹＥＳ）、処理は終了する。また、アナログ信号の入力が終了していない場合（Ｓ４でＮＯ）、処理はＳ１に戻る。 (Flow of processing of analog signal input device 1)
FIG. 5 is a flow chart showing an example of the flow of processing of the analog signal input device 1 according to the present embodiment. An example of the flow of processing of the analog signal input device 1 will be described with reference to FIG. The voltage detection unit 130 detects the voltage value of the analog input signal (S1: input / output level detection step). Subsequently, the relative value conversion unit 131 converts the voltage value of the analog input signal into a relative value (S2). Subsequently, the LED lighting control unit 132 turns on the LED 15 according to the pattern according to the relative value (S3: light emission control step). When the input of the analog signal ends (YES in S4), the process ends. When the input of the analog signal is not completed (NO in S4), the process returns to S1.
　〔ソフトウェアによる実現例〕
　アナログ信号入力装置１の制御ブロック（特に相対値変換部１３１およびＬＥＤ点灯制御部１３２）は、集積回路（ＩＣチップ）等に形成された論理回路（ハードウェア）によって実現してもよいし、ソフトウェアによって実現してもよい。 [Example of software implementation]
